Like many “Bronies” — boys and men who like the cartoon “My Little Pony: Friendship is Magic” — the 25-year-old college student turned out over the weekend for “BronyCon Summer 2012″ at the Meadowlands Exposition Center, which drew 4,000 men, women, boys and girls, many in colorful wigs and costumes.

Outside the convention center, young men danced and sang along with songs from My Little Pony cartoon that blasted from loud speakers as a video screen on a large truck showed the show’s characters. One observer said it almost felt like a Grateful Dead concert.
